A study of the rebound effect on the product-service system: Why should it be a top priority?

Abstract

The increasing intensity of competition, environmental pressures and diversification of customer demands call for integrated solutions, and this circumstance has propelled the product-service system (PSS) into a central position to satisfy consumer requirements and sustainability agendas. However, it is essential to emphasise that not all shifts toward PSS result in sustainability. Even when well-designed, PSS could generate unwanted side effects, usually referred to as rebound effects. Unfortunately, the study of rebound effects within PSS is constrained by the classical concept, which is concerned only with energy efficiency and its environmental impact. It is crucial to develop transitional awareness in observing the rebound effect on PSS by performing an in-depth assessment. This study aims to expand the discussion about the potential rebound effect within the PSS context and propose a framework for the PSS-rebound effect from a life cycle perspective. This study classifies and comprehensively depicts the rebound effect inside the PSS concept, highlighting the various features and cases/types of PSS based on current literature. Then a method is proposed to identify types of rebound effects, their causes and their period of occurrences within the product’s life cycle based on three sustainability characteristics. Case studies are provided to illustrate the application of the framework to identify the PSS-rebound effect relationship from the life cycle perspective. The result is beneficial for identifying potential rebound effects associated with PSS implementation to foster sustainability.
